About Us
Onetcall is a demonstration project co-financed by ESA (European Space Agency) regarding the thematic area: Aviation, Transport & Logistics, Maritime and Aquatic.
The service will allow end users to continue using their smartphone with their phone number without modifying their user experience in any way and at a cost that is absolutely lower than the one they currently support with other existing VoIP services.
The proposal to create and demonstrate a system like this, is made possible by the availability of an international patent registered in Europe, USA and Russia, for which the proposing team have an exclusive use license.
OneTcall is an innovative communications system, enabled by a satellite link, which, by appropriately combining technology and services already available on the market, aims to allow all users in possession of a smartphone and operating in an on board area to continue to use their device to make and receive calls from anyone with access to the telephone network, without operating limitations or variations in the usual user experience.
